DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

The aerodynamic arrow of this invention is generally referred to by the reference numeral 10 Arrow 10 includes an elongated shaft 12 having a forward end 14 and a rearward end 16. A nock 18 is mounted on the rearward end of the shaft 12 in conventional fashion. The broadhead of this invention is referred to generally by the reference numeral 20 while the fletching of this invention is referred to generally by the reference numeral 22.

Broadhead 20 includes two or more metal blades 24, and preferably, three metal blades 24. The broadhead 20 includes a pointed portion 25 at the forward end thereof. Each of the blades 24 includes a leading edge 26, a trailing edge 28, a first side 30 and a second side 32. Fletching 22 includes fletching members 34, each of which have a leading edge 36, tapered trailing edge 38, a first side 40 and a second side 42.

The first side 30 of each of the blades 24 is flat while the second side 32 of each of the blades 24 is cambered. As seen in the drawings, the cross-sectional shape of each of the blades 24 is such that the leading edge 26 thereof has a greater diameter than the trailing edge 28 thereof. The cross-sectional view of the blade 24, as seen in FIG. 2 is much like that of the cross-sectional shape of a stealth bomber or the like. As the arrow is traveling through the air, the leading edge 26 of each of the blades 24 travels straight through the air with the air passing upwardly over the cambered surface of the blade 24 to create a lift to create a rotational movement to the shaft 12. Preferably, each of the blades 24 is constructed of a metal material.

With respect to the fletching members 34, each of the fletching members 34 has a leading edge 36 and a trailing edge 38. It is preferred that the fletching members be comprised of a soft plastic or rubber material. As stated before, the fletching 22 may be used with or without the broadhead 20 but it is preferred that both of the broadhead 20 and the fletching 22 be utilized on each of the arrows.

When the arrow is released from its bow, the blades 24 and the fletching members 34 impart rotation to the shaft 12. Use of either or both of the broadhead 20 and fletching 22 increases arrow speed due to less form and parasitic drag and higher kinetic energy. The use of the broadhead 20 and the fletching 22 increases accuracy due to the rotational movement of the arrow due to stability. The fletching 22 may be mounted on the shaft in a straight fashion as opposed to the canting fletching members of the prior art. The design of the broadhead 20 is such that it provides greater arrow penetration. It can be appreciated that the broadhead 20 and the fletching 22 are compatible with compound bows, cross bows and conventional bows.

It can therefore be seen that the invention accomplishes at least all of its stated objectives.

Although the invention has been described in language that is specific certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention.
